Question edited for clarity and name of maker 'fridgerdair'.

You have a non-standard prototype model that only exists in your house. You will need a service call. The control knob needs replacing, or the burner element under the glass needs replacing.

Hold down lock for 10 seconds

You have a defective breaker. Once you replace it the oven will get the correct voltage restored.

Make sure the oven timer is set properly, if its turned off, the oven will not go on. Also check if the oven has separate fuse, it may have blown.

You didn't say what brand or model but here is a link to a youtube video for a Frigidaire oven, Other brands and models on youtube too. You will probably be able to get a replacement kit from sears parts direct if you have the brand and model number. Or an appliance parts store or ebay.

They may have simply neglected to plug it back in, Marsha. Check that first.

Good Afternoon Leslie, this is Z. Thank you for your post!

I see you are looking for information on how to remove the glass-top of your Frigidaire Cook-top (318223634). It appears above-listed model number is invalid; however, this is not a typical DIY job. I would strongly recommend connecting with a professional to narrow down the precise issue before investing in parts that may or may not be the root cause. You can often locate a qualified service provider through the manufacturer website. Best regards.

Check your incoming power with a volt meter for 220 volts at the cord terminal block.

Usually short instructions come with the glass. Just be careful about the wires not to pinch them tween the new glass and the frame. Use the type sealant they recommend.

You have a fault in the range electrical system
